Specification forming, part of Letters Patent No. 22,655, dated January 1N, 18.39.

Paddle\\'heels for Propellinfh Vessels or` i\lotor-\Vheel.\' for Machinery; and Ido here by deelare that the following is a full and exaet deseription thereof, reference heine; had y to the accompanying drawings, and to letters of reference marked thereon.

'lhe nature of myinvention eonists in providing' a revolvingl` paddle or bucket, to be attaehed to the frame-work ot the wheel in sueh a manner as to answer all the purposes of the common or Astationary paddle, and at the same time to prevent the lifting1 of the water as they leave their propelling' direction, thus Securing the ad vantage of raising the vessel when they strike the Surfaee and obviat'ing the disadvantage ol.' depressing il, when they eome out ofthe water.

It also consists in so arranging said paddles or buckets as to make them applieahle to the common water-wheel for propellin,r machinery, the.

To enable others. skilled in the art; to make and use my invention, I will proceed to describe its construction and operation.

Figure l is a pernpeetive viewof the wheel; Fig. 2, the revolving' paddle or bucket; lig. 3, an end view of the paddle; Fig. 1t, the revolvingr double paddle, which can be used in the Sallie Wheel.

l construct my wheel in any of the known forms so far as the disks or arm 4 are eoneerned, and .also attach them in asimilar manner to the Shaft. 'l`he paddle (i, Fig. 2, l make oli' boiler-iron or any other suitable material and securely attach it to the Shaft e, the ends ol'l which are turned and fitted into the disks or arms A, ltr. l, ot' the wheel, so that they can revolve freely upon their axes. \\"hen the paddles U t approach the Surface of the water, their edges will have a tendenev to enter first, which ohviates the eoneussion caused hy the striking;v of the ordinary hueket with its flat surface upon the water. 'lhey will, however, immediately after ent ering' the water adjust themselves hy means ol' the resistance of the water, so an to present their full surface and remain in thatposition until they eommenee rising', when they turn again upon their axes by their change of position in the water and pass out in a vertical direetion, thuny ohviatinel the oblique action on the rising side of the wheel and eonSequent depression of the vensel.

That I elaim as my invention, and desire to seen re by Letters Patent, is-

'lhe eenlrally-Suspended paddle or hucke't without any stop, means, ditterenee of area or of weight, for holding it. in a workin;T position, but left entirely to the aetion ot' the forces exerted upon it during the revolution of the wheel, as herein set forth.
